The story of fire on Deschutes National Forest

Creator:: Eckert, Bradley E.
Resource Type:: Capstone Project

Evaluating nitrogen fertilization and cycling in Pacific Northwest Douglas-fir plantations: a literature review

Creator:: Rasor, Christopher T.
Abstract:: There are many diagnostic approaches to evaluate the nutritional status of a forest stand. "Inference based on site and stand characteristics, visual symptoms, and foliar analysis are suggested to have the greatest utility in routine evaluations, while soil analysis and pot trial techniques should primarily be regarded as research tools...

Long-term patterns of diameter and basal area growth of old-growth Douglas-fir trees in western Oregon

Creator:: Poage, Nathan Jeremy and Tappeiner, John C., II
Abstract:: Diameter growth and age data collected from stumps of 505 recently cut old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees at 28 sample locations in western Oregon (U.S.A.) indicated that rapid early and sustained growth of old Douglas-fir trees were extremely important in terms of attaining large diameters at ages 100–300...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:: Downs, Theodore
Abstract:: Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...

Temporal and spatial variability of historic fire frequency in the southern Willamette Valley foothills of Oregon

Creator:: Robbins, Danielle
Abstract:: A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...

Methods for evaluating crown area profiles of forest stands

Creator:: Dubrasich, Michael E., Hann, David W., and Tappeiner, John C., II
Abstract:: Canopy architectures of five structurally complex forest stands and three structurally simple forest stands in southwest Oregon and the Willamette Valley, Oregon, were evaluated and quantified through crown area profiles. Mixed conifer and mixed conifer-hardwood stands across a range of sites were sampled for crown widths and heights. Crown width...

Two studies of Acer macrophyllum : I. The effects of bigleaf maple on soils in Douglas-fir forests : II. The ecology of bigleaf maple seedling establishment and early growth in Douglas-fir forests

Creator:: Fried, Jeremy Steven
Abstract:: Bigleaf maple (Acer iaacrophyllunt) is a deciduous, persistent, sprouting species that frequently accounts for as much as 20% of the basal area in Douglas-fir forests. Because of the lack of knowledge of the role of bigleaf maple in Douglas-fir forest ecosystems and the problems that it poses as a vigorous...

Clonal expansion and seedling recruitment of Oregon grape (Berberis nervosa) in Douglas-fir (Pseudotsuga menziesii) forests: comparisons with salal (Gaultheria shallon)

Creator:: Huffman, David W. (William), 1962- and Tappeiner, John C.
Abstract:: Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Above- and below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape...
